To all whom itlmay conccmi v Be it known that I, SADrE OTNINF EY,

a citizen of the United States, residing at Dayton, in the county of Liberty and State of Texas, have invented certain new and useful Improvements in a Bailer'forlvells, of which the following is a specification.

This invention relates to the new and useful improvements in a bailer v;;Eor wells.

iOne object of the invention is to provide a device of the character designed for the purpose or bailing water,.slush, and the like, from oiland other wellsi j Another object of the invention is to pro-z come overloaded, particularly when being usedas a swab. l

A further feature ment so as to vary its capacity for lifting loads.',A still further feature of the invention is to provide a bailer that may be used as a swab. v

With the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings v wherein V Figure l is a side View thereof. a p In the drawing the numeral 1 designates the barrel of the bailer which is tubular in plates having the upwardly flared centralopening 9 forming a valve seat, and also having the drain ports 10, 10. There is .a

disc valve 11, having a relatively large central opening 12, said disc being seated on a 13' which rests on the plate 6v and 3 and normally coil spring is confined in the housing holds the valve against the underside of the plate 8 and closes said drain ports.

of the invention is to provide a'bailer which iscapableot adjust fragmentary vertical sec-v tional view of the bailer and Figure 21sa' "formed with an internal annular web 3,

There an upwardly opening valve 14,

conforming to the shape of, and adapted to seatin, the valve seat 9, Attached'to this" valve there is a stem which depends through the openings :12, 7 and 4t, and whose lower end hasa cross pin, normally spacedbeneath the web 3, andadapted to engageagainst said web, to limit the ,Tl'iere'is a short tubular section attached to and depending from the lower end of the upward movement housing v3 and provided {to protect the valve stemandthe set screws 5 against injury,

and surrounding the housing thereis, in some,

cases,;the-swab. 17, sleeve likefin-form and composed-of rubberor other suitable mate- The bailer" is first let data into ar sen rials, and which closely within the" screen bore andwithdrawn therefrom, by the conventionalfbailing line 19. "As the bailer passes downwardly through the fluid, said fluid passes up through the openings 1, 7,

and 12' and lifts the valve 14: and passes into the barrel. WVhen the bailer-is pulled upwardly the valve 14 seats and the: fluid "is thereby retained in the bailer barrel and withdrawn to the ground'lsurface. In case the barrel receives an-over'fiow of fluid, the

"spring 13 will yield, permitting the valve 11 to'open'theports 10 and the excess load I will be drained out and there will,vthus, be a no danger o'f-breaking, the line. This {excess loadis most likely to occur, vwhen the swabv 17 is in use, asthisiswab fits snuglyi in the out preparatory to bringing inithe ,well.v The compression of the spring 13 may be varied, through the adjusting screws 5,

screen and is designed to clean the screen fand the capacity of the bailerthus varied so as to accommodate the" line to the load it is capable of carrying.

What I claim 1szf- 1. A bail'er including a barrel, an upward- 1y opening valve in the bottom thereof, a

downwardly opening valve at thebottom ot the barrel, a, yieldable member normally holding said last named valvefclosed.

2. A bailer including a barrel, an upwardly varyingthe compression of said yieldable member.

' I baile including a barrel, an upwardly opening valve and a downwardly opening valve arranged at the bottom thereof, and a yieldable member normally holding said last named valve closed.

4. A bailer including a barrel having a lower end plate provided with ports, an upwardly opening valve normally closing one of said ports, a downwardly opening valve normally elosing the other of said ports, a yieldable member normally holding said last mentioned valve elosed, and means for varying the influence of said yieldable member on said valve.

5. A bailer for wells including a barrel Whose lower end is provided with a valve Seat and a drain port, a housing carried by the lower end of the barrel, an upwardly opening valve adapted to co-operate with said seat, a downwardly opening valve in said housing, a yieldable member in the housing sustaining said downwardly opening valve and normally holding it in position to close said port.

6. A bailer for wells including a barrel Whose lower .end is provided with a valve seat and a drain port, a housing carried by the lower end of the barrel, an upwardly opening valve adapted to oo-operate with said seat, a downwardly opening valve in said housing, a yieldable member in the housing sustaining said downwardly opening valve and normally holding it in position to close said port, and means for varying theiinfiuence of the yieldable member on said downwardly opening valve.

7. A bailer for wells including a barrel whose lower end is provided with a valve seat and a drain port, a housing carried by the lower end of the barrel, an upwardly opening valve adapted to. co-operate with said seat, a downwardly opening valve in said housing, a yieldable member in the housing sustaining said downwardly opening valve and normally holding it in position to close said port, and a sleeve-like swab around said housing.

8. A bailer for wells including a barrel whose lower end is provided with a valve seat and a drain port, a housing carried by the lower end of the barrel, an upwardly opening valve adapted to co-operate with said seat, a downwardly opening valve in said housing, a yieldable member in the housing sustaining said downwardly opening valve and norn'ially holding itin position to close said port, a sleeve-like swab around said housing and means for varying the influence of said yieldable member on said last named valve.

In testimony whereof I have signed my name to this specification.
